皇貴妃任娘娘所居之室器物隕落，任娘娘於天啟五年十月初一日所生皇第三子，於是日受驚後遂薨逝

Translates roughly (with the caveat that my Literary Chinese sucks) as:

In the imperial consort Lady Ren's living quarters, things fell down and the emperor's third son she had given birth to on the first day of the tenth month of 1625, having been shocked on that day, subsequently passed away.

The paragraph I took that quote from begins with the description of a dragon sighting four years earlier, which might give you an idea of how reliable that source is.

Thank you for this. Didn't expect my question to get answered so thoroughly but at the same time it doesn't answer whether it was the blast shock or generic medical shock, I'm guessing blast shock given how everything in the house was rattled.
